The Desire's Radio Interferes with Head-phones?

Hi there,
I didn't believe it at first, but the GSM / 3G radio on my Desire interferes with the headphones while I listen to music, to the degree that it is, well... unlistenable. I have to activate the Airplane Mode in order to listen to music, which I think is just preposterous. I've never had that problem with any other phone.
You know that annoying noise that cellphones can induce in stereo speakers, if the speakers are connected to an unearthed socket? That's what I hear in my headphones on the Desire.
Is this due to a unique fault in just my unit, or do any more of you hear this noise?
Cheers

I hear it only when the internet connection is active - and even then it is quite low (but still there).
So all I have to do is turn off internet connection and the problem is solved.

Hi i'm glad someone else has noticed this thought it was just me
here was my thread about it:
http://forum.xda-developers.com/showthread.php?t=683024&highlight=shielding
Definitely seems like poor shielding to me. I can't believe nobody else has noticed it. Maybe because I use sound isolating headphones so it makes background noise quieter?
A very serious flaw for something I use as my main Mp3 player

Someone at your thread wrote "Apparently I had the 'only use 2G networks' option turned on! Now with 3G the issue is gone". I am actually on the countryside at the moment and unfortunately required to connect using GSM / Edge, perhaps that's what causing the noise and it will disappear on 3G? Either way, it shouldn't be there in the first place

Exactly. This is a basic requirement.

Just under that option is the option to turn off mobile internet...try that instead, at least you still get phone calls and messages that way.

I just replied in the other topic. I have this problem withg several in.ears, and disabling internet or enabling airplane mode doesn't help at all. As long as the phone plays sound (and for four seconds afterwards - ie, as long as the "soundcard" in the phone is turned on) it makes a hissing sound, making it completely unfit for music and to some degree tv series/movies too.
edit: Guess I should mention that the volume is also too loud, there is NO way I can have it more than two or three steps from the bottom, and between the lowest step and "silence" (ie. only hissing) there is quite a jump in dB.

What product are you using? I've only noticed this on products of poor quality. Both my AKG and MW600 have no problems with it at all.

As I said in the other thread, I'm using a good quality closed headset and there is no hint of hiss.

I have the same problem with a pair of Creative Aurvana in-ears and a pair of Sennheiser CX300. While they are not the most expensive sets you can buy, they bot sound fine while used with other devices - ie. a Nokia 5800, an iPhone 3g and my old Creatove Zen Micro. It is most certapnly the Desire that is the problem.
I expect to hear noise wih low ompedance in-ears on cheap laptops and non-branded china players, but not on somathing claiming to be a great multimedia phone at a pricetag of $620 (unbranded in Norway).
This prolem most likely stems from bad intrnal isolation of the audio chip/wires/jack, and would ofc not be heard with a BT headset... As to your AKG, unless they are low impedance in-ears, whether you hear noise in them or not is equally uninteresting.
I would really like someone with a good pair of low impedance headphones and good hearing to say that their phone is NOT producing this white noise. My pal didn't think his did, but it sure does. If it is just faulty units, it means it can be fixed, so I don't have to spend a few months getting my money back and find another phone to buy.

[Q] HD7 speaker hiss, could you check for me?

Hi there. Just noticed with my HD7 that after its made a noise, say for example the keyboard click which i love by the way, my rear speaker has a hiss for about a second afterwards. Could someone else with a HD7 please hold their phone with their rear speaker to their ear and then get their phone to make a noise so that I can find out if it's my phone or a feature of the HD7?
To be honest the reason I'm interested in this is the speaker hiss that I'm hearing here I think might be related to the bluetooth audio quality issues I have, long shot I know.
Thanks

Confirmed, I hear the hiss too. I think it's the audio file for the click sound. After the click sound is made, the file continues playing for a few seconds.

Cheers for that.. Seems to happen when you pause music or anything else really. Ah well, first gen poor quality hardware I guess.. I knew I was gonna take the hit.

I thought this was standard on everything, it definitely happened on my last 2 android devices.

Yeah, it's not a big deal at all.

Yeah for sure not a big deal, would never notice it if I hadnt randomly had it up to my ear.. Like I say just grasping for reasons why the bluetooth audio might be a bit ropey. The same hiss was heard over a friends bluetooth headset, sorry cant remember the make (my parrot doesnt have the hiss but does have a crackle, go figure).

My Jabra Halo, and my car via a FIPO device both have the his over bluetooth, occasionaly stuttery audio, never crackles though

HTC One X Audio Hiss

Seen quite a few topics on this, seems no one has a solution.
What I'm trying to accomplish with this is to see if EVERY HTC One X has this problem of a hissing noise in the background.
The hissing noise sounds somewhat like television white noise, and is apparent when playing music at low volume and during quiet parts of a song.
Testing Method:
i) Using headphones/earphones/whatever that plugs in the headphone port,
ii) Play music or other audio.
iii) Turn volume down to zero (0%)
iv) Listen for the noise.
Repeat method with no headphones i.e. with speaker, and put speaker up to your ear (very close). Try and listen for the noise.

my one x has the issue too.

As far as i know this is not an issue and it's normal, try doing the same thing with any other device and you will hear the same thing, may be hard to notice sometimes but it's there ( I didn't notice this on my HOX until i read your thread )

I do have this hiss on my one x.It can easily be heard when the music is stopped and this hiss continues for a small second!

It drives me mad as I tend to listen to music on lower volumes compared to others...
Sent from my HTC One X

if it is for 2-3 seconds and then it stops, it's normal, not an issue, due to a low voltage signal the sound chip sends to audio device (whether that would be a simple earphone, or a full support Bluetooth audio kit) to announce that the sound broadcasting is finished... (fade out noise)

Same here.

At 0% volume mine does not hiss, however if I play a song then pause it there is a faint hiss for a second or two then it stops completely.

Here's another one, plug the charger in and here the buzzing/feedback through the earphones when charging...

No, the problem that I'm experiencing and trying to see if others experience is whether the hiss is happening DURING the music. I understand if you listen to music at above 50% you most likely will not hear it during the music.

Yes, I have got the same problem and it is caused by very poor SNR of One X DAC or analog circuit.
It is very annoying for me, as I use sensitive IEMs and my old HD2 has not got this issue at all - I just find hard to accept that I have to hear audio noise in 2012 flaghsip device. There are some workarounds possible that can POSSIBLY at least partially mitigate the problem:
1. Use less sensitive headphones
2. Use some kind of attenuator, like:
http://www.ebay.co.uk/itm/Sound-lev...13488602?pt=US_Headphones&hash=item1e6f218cda
and increase listening volume at the same time

Issue confirmed. Could not believe that in this day and age I am confronted with such an obvious hiss on this top-of-the-line HTC phone.
Coming from the S2, I have not been impressed with the quality of the One X. I like the screen though, when I can't see any yellow spots, that is.

Will an external DAC help with this problem, if even usable with a phone?
Sent from my HTC One X

I probably should have said in my original post but yes I have the issue and noticed it....
Alternative was to use Bluetooth, I personally might get an APT-X adaptor thats portable so I can connect to my home cinema system or car stereo through the jack input....

I wonder if there's any One X without this problem, such as newer batches etc

If you can feed it a digital signal, then yeah, by all means it would help. I've not looked into it, I dunno if it's possible.

about 3 peoples said there it is normal so why continue this ? lol it have everything that make music,sounds.. its normal due to low voltage to earphones and there is currently no technology that can stop this noise...

Larger sample size. And also speaker out has this problem, not just headphones. And why other phones don't have this problem?

using music app or tune in radio connecting to my cars aux in via 3.5mm connection cable to utilize audio device and loudspeakers in car, and it is even more noticeable.. (the sound is great though) also you hear hiss and noises as inerference effect from the the engine clearly in silence between track changes

I have it as well, but im pretty sure iv heard the exact same noise on most consumer devices ive had like my ipod and old s2.. didnt even think about it till i saw this thread.
If it bothers you that much just email htc and see what they say...

bad audio through car stereo

Hey all,
For some reason unbeknownst to me whenever i plug in my a100 to my Cadillacs stock tape adapter it sounds very distant. Like a small radio sitting on a shelf at the other end of a warehouse is the best way i can describe it. When hooked up to my headphones it sounds amazing but when i use the tape adapter it sounds horrible. Both mine and my GF's phones sound fine but the tablets sound is borderline unbearable. Ive also tried different media players and Pandora with the same result. Also i dont have it charging so im pretty sure its not cross interference. If it were it would pop and sound scratchy witch it doesn't the audio is clear, but like i said sounds really distant. Plz any help or ideas would be much appreciated.

The only thing I can tell you is play around with the jack once it is in the tablet. I know my headphone jack is long and if I push it all the way in it sounds distant like that. I have to pull it out a hair (yes only that much) and it works fine..... But a tiny bump and it sounds bad..... Headphones e jjacck was defective on my acerr when I got it. Sent it in and it works but is crap. I use my infuse for music anyway. That Wolfson DAC sound board with voodoo..... Amazing.

i suggest to get a new radio with a mini jack on the front they are less than 50 bucks. and if you shop around you can find one that will play mp3 cds that hold like 250+ songs depending on the compresion

I had the same problem in my Mercedes. Go into Settings and turn off the dolby mobile and give it another try. It worked for me. I'm using an A2DP bluetooth adapter in my aux port as well, so there were no physical issues causing my problems.

You could try to up the gain in audio settings if your using power amp

Sound is the fatal flaw of the G3

I really like this phone, everything about it is great for me EXCEPT the sound quality. Anything that has to do with the headphone jack is an absolute disaster.
First off I have not experienced the dreaded AUX problem but I have experienced random pausing and skipping - as if I was pressing music controls on my headset - both in my car and on my headphones. I think a headphone jack is starting to wear?
Next I have experienced terrible distortion and static in the left channel, that was until I rooted and Installed Viper4Android. While the problem didn't go away entirely its much better than stock.
Im using my g3 with 3 or 4 devices....
My Acura's line in with Subs/Amps ect.
Shure SE846 In ear monitors
Fiio e6 amp (with the shures, sometimes helps sound quality)
Bluetooth to my Bose Soundlink
The flaws of the g3's sound output are noticeable on any of these, even the bluetooth soundlink and ESPECIALLY, on the SE846 direct.
I created this thread because I dont know what to do, its apparent I am an audiophile and care about my sound quality and youd think Id invest in some sort of MP3 player (I do have a Clip+ ) but I really enjoy using spotify. Should I buy a DAC and just avoid the g3s sound card all together or call and fight with LG and see what they can do?
Is anyone else having these problems? I have the Verizon Device.

I use Westone's connected through a Sony SB52. I haven't noticed any issue except that I like Sony's Walkman app better on my Xperia than LG's player.

I'm fairly picky about music quality and I haven't noticed any issues at all with my HD419s (the only headphones I have right now). Audio quality through aptx bluetooth directly to a car amp and polk component speakers is as good as one would expect too. No skipping or pausing with LG's app. Is that happening when your screen is on? Try turning it off, maybe it's a screen issue? Or maybe it's a glitch with the app you are using? The only problem I had with it was how quiet it was with headphones but the fix with root worked well.

There are several threads about the strange hissing sound - which I also got myself. LG has told me that they're working on fixing it and that it's a known flaw in the current ROMs.

I just got mine and I think this is the best sounding phone I have ever heard. Of course my expectations were very low after my experience with Apple and Samsung.
This opinion is coming from a very jaded HiFi gearhead so your mileage may vary.

The problem I'm facing..
There is noise+distortion+hissing during call
And when headphones are connected I cant understand or listen any thing I only hear wired noises..
Any fix guys ?
Dont know if its technical or software based issue

The sound quality has been noticeably bad for me using headphones also, bluetooth isn't too much of a problem and works fine.
I just got my headphone jack replaced free from LG (as it was doing the random skipping thing) - I quoted that it was a known problem (i mean look on XDA for all the threads) and as my phone was under warranty, i flashed stock firmware and sent it back - when i got it back in 48 hours it was replaced and working. They even cleaned the screen for me lol.
I don't use a headset, only headphones, and the quality is most noticeable on my sennheiser hd800s, but also on my beyerdynamic headphones. Install Viper audio and it improves slightly.

I got mine replaced today as well.
New phone bingo !!
